Corner beam column joint for square tubular column and H-shaped steel and assembled connection part and construction method for corner beam column joint

Abstract

The invention discloses a corner beam column joint for a square tubular column and H-shaped steel and an assembled connection part and a construction method for the corner beam column joint. The corner beam column joint comprises the square tubular column, H-shaped steel beams and the connection part; the connection part comprises a first cross-shaped connection assembly, two second U-shaped connection assemblies and third T-shaped connection assemblies; the first assembly is arranged at the edge of the square tubular column, the two second assemblies are arranged on the corresponding sides, and a wedge-shaped groove is formed between a bottom plate of each second assembly and the square tubular column; small fin plates of the first assembly and wedge-shaped fin plates of main plates of the third assemblies are correspondingly embedded into different wedge-shaped grooves and locked in a matched mode; the first assembly is in fastening connection with the second assemblies through bolts, and the third assemblies are in fastening connection with the second assemblies through bolts; the first assembly and the third assemblies are in welding connection with the edges of the square tubular column respectively; the second assemblies are welded to the ends of the H-shaped steel beams. The corner beam column joint further comprises a third H-shaped steel beam. According to the corner beam column joint, the connection part is novel in design, and through the special wedge-shaped self-fastening type connection structure, the condition that the steel beams and the steel column slide can be prevented, and the sliding stress can be avoided from being generated; the components are all machined in a factory, and welding is not conducted on the site.

Description

Background technique [0001] Prefabricated steel structures have become a hotspot in the development of the construction industry due to their high degree of industrialization, light weight, high strength, good seismic performance, fast construction, reusability, and low pollution. At present, square steel pipe columns and H-shaped steel beams are the most common vertical and lateral stress members, and their connection forms are mostly welded or bolted. To realize the assembly of the steel structure, it is first necessary to realize the productization and standardization of the components that make up the main body, especially the assembly connection of the beam-column connection nodes. Steel structure beam-column joints are further divided into four-beam-column joints, edge beam-column joints and corner beam-column joints. For corner beam-column joints, the structure is more complicated and the assembly precision is high. The angle beam-column joints involved in the prior art...

Problems solved by technology

Steel structure beam-column joints are further divided into four-beam-column joints, edge beam-column joints, and corner beam-column joints. For corner beam-column joints, the structure is more complicated and the assembly accuracy is high. The angle beam-column joints involved in the prior art have There are many connecting components, poor interchangeability, no productization and standardization, on-site welding in the assembly of nodes, complex construction methods, and difficult to control assembly accuracy
